Abstract: The significance of the appliance switch heating test is to monitor the heating of the sample itself when the switch installed on household and similar appliances is in normal or abnormal working condition. By measuring the heating temperature, we can judge whether the electrical structure design of the switch is reasonable, whether the material selection of each part of the switch is qualified, whether the switch is safe in use, etc.
